IRanges

As you've learned in the previous chapters, you can store sequences with their own alphabets, order, and focus on certain intervals of these sequences. To extract sequence intervals, you use ranges. The Bioconductor package IRanges comes in handy with its function IRanges(), which creates a vector representation of a sequence, used to facilitate subsetting and annotation.

The IRanges package has been already loaded. To help you with this exercise you can check the documentation of IRanges().

Fill in the blank:
